Jamestford:

I find it helpful to flash the chip with a simple program to turn on all LED's just to ensure all of your LED's work before moving on just in case you put an LED in backwards.

Light Em' Up Program

#include <avr/io.h> /* AVR library to define pins, ports, etc */
int main(void)
{
DDRB = 0xff; //Set port B pins as all outputs
PORTB = 0xff; //Set all Port B pins as High
return 1;
}

Jamestford: Resistor / Ohm Tutorial

I had a really tough time wrapping my head around the resistors and how you figure out which one to use and ran across this tutorial which was extremely helpful. http://vimeo.com/15395291
